Here's How to Use a Speed Square

A speed square is really an invaluable tool when it comes to easily measuring angles for building your
shed. As you can see from the picture above, the angle I need to cut is 20 degrees.

It is just a simple matter of placing the outer corner of your speed square against the wood
you need to measure, then moving it until you get your desired angle on the inner edge of the
board you are measuring.

As you can see, the plans for this gambrel shed truss call for 20 degree cuts to be made on the
top truss members. Knowing how to make these measurements truly is
an easy accomplishment using a swanson speed square.
